ABSTRACT:
An electronic hearing device for stimulating the auditory nerve by way of implanted electrodes wherein sound signals are converted to electrical signals which are divided into separate channels according to their frequencies. The signals of each channel are amplified and applied to the electrodes. The relative amplifications of each channel, after taking into account a threshold amplification, have a ratio of 6 to 7 dB/octave from the channel having the lowest center frequency to the channel having the highest center frequency.
